The unique id problem come up again and again. The automatically generated unique id will benefit web author with sql row id object id and may be some others With a view that zope will be run over the network with distributed storage across the net, I would like to suggest we implement a unique id server which can be a zope server serving on another port and serialize all request and return the globally unique id. Does this work? I also suggest zope can be configured to automatically get the object id from this service and have globally unique object ids. Rgs, Kent Sin
